4 claims. (ci. 15-202) This invention relates to a paint brush and moreAparticularly to a paint brush provided with a plurality of removablebristle units.

Prior art attempts at producing a paint brush with removable bristlecarrying units have failed to produce a satisfactory brush for variousreasons. A major disadvantage of the prior art is .the failure toproduce a satisfactory means for retaining the removable bristlecarrying units in association with a handle member. Most such prior artattempts have failed. to providea surfciently positive bristle retainingmeans without unduly complicating the device vand unduly raising thecost thereof. With extended use of most prior art devices, theconnection between the bristle sections and the handle member tends ytobe weakened, with an ensuing possibility that bristle carrying units mayfall from the handle member While in use.

It is an object of this invention to provide a sectional paint brushhaving a bristle carrying unit adapted to be used either alone or incombination with other such units to form various size brushes.

Another object of this invention is to provide a removable and/orreplaceable 'bristle carrying uni-t for a paint brush thereby expeditingeither the cleaning of paint biush bristles after use, or thereplacement thereof should the original bristles become .worn

Still another object of the invention is to provide a paint brush havinga permanent handle and ferrule portion and replaceable bristle sections,wherein said bristle carrying units may be used in various sizes othandle holders, thereby eifecting a more economical use of the variousbrush elements.

An -additional object of this invention is to provide a paint brushhaving a permanent handle and ferrule combination and removable bristlecarrying units, with means whereby said brush may be varied as tothickness and/ or width.

Other objects and advantages of the invention relate to variousIfeatures of construction and :arrangement of parts which will beapparent from a consideration of the following specification andaccompanying drawing, wherein:

Figure 1 is an elevational view, partially in section of one embodimentot this invention;

Figure 2 is a prole view, partially in section of the structure shown inFigure 1;

Figure 3 is a sectional view taken on line 3--3 of Figure l;

Figure 4 is a sectional view taken on line 4--4 of Figure l;

Figure 5 is a perspective view of one of the bristle units utilized inthe instant invention;

Figure 6 is a perspective view of a bristle unit supporting plate;

Figure 7 is an elevational view, partially in section, and partiallybroken away of va further embodiment of the instant invention; and

Figure 8 is a partial sectional, plan view of a further 2 embodiment ofpaint brush ferrule yadapted for use with the instant invention.

Referring now to the drawing wherein like or corresponding parts aredesignated .with the same reference numerals, there is shown in Figure 1.a brush comprising a handle 12 including a removable clamp or ferrule14, a brush section .16 which is composed of a plurality of bristlecarrying units 18 each of which is composed of a rubber head portion 20having a plurality of bristles embedded therein. i

The handle 12 comprises a hand engaging portion 22, and a widenedportion 24. A bristle unit supporting platef'26,` preferably though notnecessarily, made of metal, is anchored within a slot formed in thewidened portion 24 by means of rivet-like pins 28 anchored in saidwidened portion 24 and extending through holes 30 formed in said supportplate 26.

The support plate 26 is in turn provided with a pair of bristle unitcarrying iingers 32 anchored .thereto and extending laterally therefromfrom both faces thereof. The ngers 32 carry the head portion `20 of eachbristle carrying unit `18 by passage through a'pair of holes 34 lformedrin each of said head portions.

.In accordance with the embodiment shown in Figures 1 to `6, t-hebristle units `18 are held on .the ngers 32 by means .of the removableferrule 14 which surrounds the widened handle portion 24 and said units:18. The lferrule 14 is removably held on the handle 12 by means of oneor more sets of headed, cooperating screw members 36 and 38. TheKthreaded male :and female members extend through suitably sized holesin the tierrule 14, the widened handle portion 24 and the supportingplate 26 respectively.

In order to remove the bristle units 18 from the handle 12, thecooperating screw members 36 and 38 are disconnected `from :one anotherwith a screw driver or .the like, removed from the assembly and then theferrule 14 is then slid .either up or down until the bristle units arefree therefrom.

In Figure 7 there is shown another embodiment of the instant invention.This embodiment makes it possible to use a plurality of bristle unitseither by themselves in a brush no wider than each unit, or in a brushhaving twice the width of each unit, thereby rendering a given sizebristle unit applicable to various size brushes. In accordance with thisembodiment, a modied bristle unit supporting plate 26 is tixedly.anchored in the )widened handle portion 24 by the pins 28 in the samemanner as in the embodiment shown in -Figures 1 through 6. However themodiiied plate 26 is provided with two pairs of bristle unit supportingAlingers 40 .and 42 analogous to the single pair of tingers 32 on theplate 26.

An individual bristle unit 18 is mounted on the respective pairs ofngers 40 and 42, whereby the width of the brush is made up of twobristle units instead of one, as is the case in the aforedescribedembodiment. Thus with the embodiment shown in Figure 7 it is possible touse a particular bristle unit in conjunction with either' the handle12', as shown, or in conjunction lwith a handle of half the width.Accordingly, a given set of bristle units has utility in different sizebrushes.

Figure 8 discloses a modified fer-rule 14 adapted for use .with themodification shown in either Figures 1 through 6 or Figure 7. 'I'heferrule 14 consists of a pair of strips of metal or the like 44 and 46shaped so as to cooperate :with the widened handle portion 24. Thestrips 44 and 46 are held together by a suitable latch means, consistingfor example, of a hook 48 and a cooperating idetent 50 located at theopposite ends of the ferrule.

It is pointed out that the fet-rule 14 may be formed as a single splitring having only one latch, instead of a pair of strips 44 and 46, and apair of latohes.

In accordance with the instant invention there is provided a `brushhaving detachable and/or interchangeable bristle which may'be readilyremoved trom a handle for purposes of cleaning. After removal from a handle the instant bristle units may be completely immersed in a solventfor cleaning purposes.

While I have shown and described certain embodiments of my improvementsfor the purposes of illustration, it will be apparent that variouschanges can be made .therein without departing `from lthe spirit of theinvention.

What is claimed is:

l. A brush comprising a handle portion, a widened portion of oblongformation having curved ends integral with one end of said handleportion and a longitudinally extending slot centrally of the bottomsurface thereof, a plate anchored in the slot and extending from lsaidwidened portion in vertical relation thereto, a plurality of pinsiixedly mounted on said plate and extending laterally therefrom, a brushsection comprising a plurality of bristle units, each of said unitscomprising a number of bristles anchored in a rigid head member, that isof a length equal to the length of said widened portion and havingcurved ends conforming to the curved ends of said widened portion, saidhead member having a plurality of holes formed therein and extendingtherethrough, said .4 pins extending through said holes whereby saidbristle units are removably mounted on said plate, and means attached tosaid widened portion for preventing removal of said bristle units fromsaid pins.

2. A brush as set fonth in claim l, wherein said last means consists ofva -ferrule removably attached to said widened por-tion and extendingbeyond the bottom sur- -face thereof in overlapping relation with thehead portion of said bristle units.

3. A brush as set forth in claim 2 wherein said vferrule is Iheld onsaid widened portion by a screw extending through the ferrule and thewidened portion.

4. A brush as set forth in claim 2 wherein said ferrule is provided withseparable end portions, and means retaining said end portions connectedtogether.
